问题描述
我有一个应用程序 NSStatusItem 。
它有几种不同的模式，
It has a few different modes, each of which require an external process to be launched, during which the icon is simply highlighted, and appears to be frozen.
我想使用 -setImage ：方法（或合理的传真）来显示在网络应用程序和OS X中常见的微调框线条。
I want to use the -setImage: method (or reasonable facsimile) to display something along the lines of a "spinner" commonly seen in web applications and all over OS X.
有没有任何本地方法来完成这个（例如 NSProgressIndicator ？的一些实例？）或者必须通过循环一组图像手动显示动画吗？
Is there any native method for accomplishing this (e.g. some instance of NSProgressIndicator?) or must I manually display an animation by cycling through a set of images?
无论如何，我将如何实现？
In either case, how would I implement?
推荐答案
动画（而不只是一个静态图像），你可能需要使用 -setView：，并给它一个自定义视图（然后动画本身）。您可以使用合适配置的标准 NSProgressIndicator （即设置为 NSProgressIndicatorSpinningStyle 样式等）。 ）作为自定义视图。
In order to have it be animated (and not just a static image), you'll probably need to use -setView: and give it a custom view (which then animates itself). You might be able to get away with using a suitably-configured standard NSProgressIndicator (i.e. set to NSProgressIndicatorSpinningStyle style, etc.) as that "custom view".
但是，如果NSProgressIndicator标准尺寸不能正常工作，那么你可以查看我的（BSD许可），这是一个旋转NSProgressIndicator的克隆，可以设置为任意大小和颜色。
But, if the NSProgressIndicator standard sizes don't work well, then you can check out my YRKSpinningProgressIndicator (BSD-licensed), which is a clone of the spinning NSProgressIndicator that can be set to arbitrary size and colors.
